Anaplasmosis - Anaplasma phagocytophilum

Anaplasmosis is caused by the bacterium Anaplasma
phagocytophilum and is transmitted to humans by tick bites primarily from
the black-legged (deer) tick (Ixodes scapularis) and the western
black-legged tick (Ixodes pacificus). It was previously known as
human granulocytic ehrlichiosis (HGE) or human granulocytic anaplasmosis
(HGA). Typical symptoms include: fever, headache, chills, and muscle
aches. Usually, these symptoms occur within 1-2 weeks of a tick bite.
